I have myotonics, boers, and crosses. From my experience, they faint at 66% myotonic or higher. 
Well thanks. These are Momma raised and over 8 weeks old. I'm not even sure what age they areI've had goats for over 10 years. Welcome to insanity!
Definitely find out if the kids are weaned. If they are dam raised, wait until they are 8 weeks. If they are bottle raised and under 8 weeks, make sure you know what you are getting yourself into before you take them.
For the dewormer, you need to find out which worms you're dealing with before you deworm. Here in the states there is a lab you can mail fecal samples to, but I'm not sure about Canada. If you are very, very lucky, there will be a vet in your area experienced with goats. Even if they are not experienced with goats, they will still be able to run a fecal for you.
Goats for the most part don't need a lot of medical care, but you do need to be prepared. Like most animals, they pick the middle of the night, a rainstorm, or a blizzard to need help, just to keep us on our toes and make us crazy
There are lots of online resources, the very best I have found is https://tennesseemeatgoats.com/. There is a wealth of information on there, my go to whenever I have a problem. I am lucky enough to have an experienced vet about an hour away, but when a goat gets sick, it needs immediate attention, and you're mostly handling things by yourself. Also, ask around your area to see if there is anyone with goats near you that can show you the ropes. Giving vaccinations and figuring out dosages for dewormers and meds can seem intimidating, but it's not that hard. You'll be giving shots like a pro in no time! Also, get together a med kit with the things you'll need in the middle of the night when the stores are closed.
Don't their teeth constantly grow like horses teeth?my fainting/Nigerian wether has yet to faint. But i can't confidently say that yours wont either..
What kind of wormer are you using?
Goats can drink up to a gallon of water a day. So i always make sure they have water 24/7. Just make its up high enough so they can't poop in it
As for supplements I give mine meat maker goat minerals. And I have it out for them 24/7 as well, They wont eat it up right away like grain so you don't have to worry about buying them minerals every week.
and if they're looking bloated i'll leave out some baking soda as well for them.
And try and avoid mineral blocks. They can damage their teeth while trying to chew on them..
You can have baking soda out for them as long as you'd like, just like the minerals. but I only provide it if one of my goats are looking bloated. It's up to you how much you want to provide.
here are some good cheap ideas that caught my eye, Also if you ever come across wooden spools snatch them up! Goats love them~
Awesome ideas for playing on..
